Anthony Joshua and Wladimir Klitschko are set for a heavyweight boxing blockbuster at Wembley

PAAnthony Joshua and Wladimir Klitschko square up at their press conference on Thursday.

Two decorated heavyweights clash in front of 90,000 fans, a post-war record, at Wembley Stadium on Saturday in a bout dubbed the biggest British fight of all time by Matchroom Sports promoter Eddie Hearn.

The young and hungry Anthony Joshua, a 2012 Olympic champion, defends his IBF world heavyweight title against all-time great boxer Wladimir Klitschko who, at 41, is 14 years Joshua’s senior.

“I win, it’s not complicated,” a confident Joshua said a press conference on Thursday. “This isn’t rocket science. This is just a fight. Let’s strip it right back to what it is — a young lion, ferocious, hungry, very determined.

“I left no stone unturned in training camp. We do talk about experience, but even when I was fighting guys with lesser experience I was preparing for this. I’ve prepared since day one for this.”
